Question

Explain hybridization of central atom in $Cl{O}_3{}^{-}$

Answer 1

Identify central atom,

Hybridisation $=\frac{1}{2}$ [Valence electrons $+$ No. of monovalent atoms $-$ cationic charge $+$ anionic charge]

For ${ClO}_3^{-}=\frac{1}{2}[7+0-0+1]=\frac{8}{2}=4={sp}^3$

Ans :- ${sp}^3$ hybridisation.
